IUCN conservation status
They're the most northern primate species in the world! In winter, their coat's thickness increases to allow them to withstand the cold!
A Varied Diet Depending on the Season and Availability.
Being omnivores, Japanese macaques prefer fruit, berries and nuts. They also eat mushrooms, insects, snails, crustaceans and bird eggs when these are available. In winter, they survive mainly on fat reserves and feed on bark and buds.
Data Covering more than 50 Years
They're probably the most studied primate species in the world. Among other observations, researchers watched a young macaque wash sand-covered pieces of sweet potatoes that the scientists had thrown on the beach to lure them out of the forest. This behaviour was then adopted by the other members of the group.
A Hierarchy Based on Females Rank
Protected, they're still Sensitive to the Deterioration of their Habitat
Confined to certain Japanese islands, Japanese macaque populations have enjoyed a high level of protection, especially since they were declared a " Natural Treasure of the Nations " in 1970. But deforestation of their habitat, and occasional conflicts with humans, threaten their long-term survival.
